Brushstrokes paint tales of painful disease

In the courtyard of Beijing's Xuannan Bookstore, an unusual art exhibition is quietly unfolding. Each painting features figures wracked with pain: gripping knees, clutching elbows and wincing in discomfort.

This public-interest exhibition is dedicated to raising awareness on tenosynovial giant cell tumor (generally benign growths), a rare joint disorder.

The artworks are the result of a collaborative effort by patients, their families, medical professionals and artists.
